IMPRovEMENT' IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of thersame.

To all whom it may concern.-

Be it known that I, DAVID HENRY GoULD, ofv

Troy, in the county of Rensselaer, audbtate ot' New York, have invented certain new and useful Improvernents in Water-Wheels 5 and I do` h'ereby declare the following to bea full,4 clear, and exact description ofthe same, reference being hereby had to the accompanying drawings, which form and make a part of this, my specification.

Like letters represent and refer to like or corresponding parts. Y l

Figure 1 represents a section of a water-wheel, and

Figure 2 represents sectional views of the guides and buckets, showing my invention and improvements,

'more fully hereinafter describedl and set forth.

rlhe nature ot' my said invention and improvements consists in the guide, in combination with a. water- `wheel, substantially in the mannerand for the purposes hereinafter fully described and set forth.

lt also consists in" the bucket, combined with a water-wheel, substantially in the manner and for the purposes hereinafter` described and set forth.

p 'lo enable others skilled in the art to which my invention relates, `tomake and use the same, I will here proceed to describe the construction and operation p thereof, which is as follows, to wit:

The object ofthe first-named improvement, that is, the guide, is to render all wheels, using gates of the class shown in the accompanying drawings, more effective, by making the contraction ofthe vein, or stream, or current of water more perfect in p assingybetween the guides, and avoiding loss of power that would otherwise occur in eddyng motion occasioned bythe sudden enlargement below the gate a, `u', becoming cv; it being a principle of hydraulics that any intermediate enlargement of the opening through which `the water passes is detrimental to the. useful ettect.

i This guide A A, iig. 2, is thrilled by joining the pointu, at the extremity ofthe flange whichsupports the gate C, with the point d, 'near the lower extrennty ofthe guide A, all of which isfnlly shown at Iig. 2 ot the drawings.

The bucketB B, fig. 2, is formed by casting, or

otherwise attaching to the backI or rear side of the bucket B, the additional plate b, which may be of any size, strength, and shape that future experiment may deem best to use.

- The object ot' making this bucket B, as shown in any form of wheel, guide, or bucket, where the parts are cast solid or with a core, or to the extent of the use .of either beyond the" ordinary guide and bucket, composed of a single thickness of thin plate of castiron or other metal, neither to the combination of the two improvements in the same wheel.

Having thus Vdescribed the 'nature of my said invention and improvements,

\Vbat'I claim as new, and desire to secure by Letters Patent ofthe United States, is

1. The guide, or chute A A, formed of a large exterior and a small interior circle, the Segments thereof meeting below, at the extremity of thefguide, and terminating above, remote from each other; so as to give the form of a curved wedge, presenting a convex and a concave surface, in the manner and for the purposes substantially as herein described and` set ibi-th.

2. 'lhe buckets B B, of the`water-wheel, made on In testimony whereof, I have hereto set my hand,
